Abstract

To investigate the line edge roughness (LER) and linewidth roughness (LWR) impact on critical dimension (CD) variation for gates, three characterization models of LER/LWR are present, the LER/LWR line edges with the self-affine behavior are simulated, and the relationship between the CD variation and the parameters of LER/LWR are found out. The results show that without any other sources of variation, LER/LWR can cause gate line-width variation, and its effect on the CD variation is of first-order.
